    This commit is to add config option

    timing values set by the 1st stage bootloader, instead of the hard-coded
    values in the Zynq NAND driver.

  • 1d9654dc4   mtd: nand: denali_dt: add a DT driver ... Browse Code »

    A patch for NAND uclass support was proposed about half a year ago:
    https://patchwork.ozlabs.org/patch/722282/

    It was not merged and I do not see on-going work for this.

    Without DM-based probing, we need to set up pinctrl etc. in an ad-hoc
    way and give lots of crappy CONFIG options for base addresses and
    properties, which are supposed to be specified by DT. This is painful.

    This commit just provides a probe hook to retrieve "reg" from DT and
    allocate private data in a DM manner. This DT driver is not essentially
    a NAND driver, in fact it is (ab)using UCLASS_MISC. Once UCLASS_NAND is
    supported, it would be possible to migrate to it.

  • ff93c2826   nand: sunxi: Add options for the SPL NAND configuration ... Browse Code »

    The SPL image needs to be built with a different ECC configuration than the
    U-Boot binary.

    Add Kconfig options with defaults to provide a value that should work for
    anyone, but is still configurable if needs be.

  • adc706b2f   mtd: sunxi: Change U-Boot offset ... Browse Code »

    The default U-Boot offset for the Allwinner SoCs was set to 32kB.

    This was probably to try to maintain some compatibility with the current
    image that we build for the MMC where the U-Boot binary is also located at
    a 32kB offset.

    However, this causes a number of issues. The first one is that it prevents
    us from using a backup SPL entirely, which is troublesome in case where the
    first would be corrupt (especially on MLC which have a higher number of
    bitflips).

    We also cannot use the original MMC image on the NAND, because we need to
    prepare the SPL image to include the ECCs and randomizer settings, which
    reduces the interest of setting it at that particular offset.

    It also prevents us from upgrading and flashing the U-Boot and SPLs
    independantly, since it's very likely that it will fall in the same erase
    block.

    Since that default wasn't used by any board, change it for 8MB, which will
    be in an erase block of its own, all the erase blocks being multiple of
    two. The highest erase block size we encountered is 4MB, which means that
    in this particular setup, the first and second erase blocks will be for the
    SPL and its backup, and the third for U-Boot.

  • f78038dc0   mtd: nand: build MXS driver for MX7 as well ... Browse Code »

    The i.MX7 has the same GPMI controller as i.MX6 and is covered by the MXS
    driver. Tell Kconfig that we can use this driver on the MX7 platform (the MXS
    driver already has the few i.MX7-specific changes needed for basic operation
    and the board itself sets the pinmux correctly).

    Tested on i.MX7D with the Sabre board and a NAND Flash soldered to U12.

  • 80ef700f8   spl: nand: support redundant u-boot image ... Browse Code »

    On modern NAND it's more than recommended to have a backup copy of the
    u-boot binary to recover from corruption: bitflips are quite common on
    MLC NANDs, and the read-disturbance will corrupt your u-boot partitition
    more quickly than what you would see on an SLC NAND.

    Add an extra Kconfig option to specify the offset of the redundant u-boot
    image.

    The SYS_NAND_U_BOOT_OFFS is quite generic, but the Kconfig entry is forced

    Make CONFIG_SYS_NAND_U_BOOT_OFFS configurable through Kconfig, just like
    SYS_NAND_BUSWIDTH_16BIT this is only enabled on some SoCs using depends,
    to avoid double defining it for SoCs which have not yet moved to Kconfig
    for this.

    Having this in Kconfig is useful because this is something which may
    differ from one board to the other even when using the same SoC.

  • 6a08d65ac   sunxi_nand_spl: Remove NAND_SUNXI_SPL_SYNDROME_PARTITIONS_END ... Browse Code »

    We only ever use syndrome mode for the partitions which contain the SPL,
    as that is required for the BROM to be able to read the SPL.

    Instead of using some arbritray limit for deciding whether or not to
    use syndrome, be smart and check if u-boot-dtb.bin is directly behind
    the SPL, if it is not then it is on its own partition and we should not
    use syndrome.

    Note the reason why we only use syndrome mode for the SPL is because it
    comeswith weaker randomization, introducing a risk for more bit errors,
    so we want to avoid it when possible.

  • e52686168   sunxi_nand_spl: Rename SPL_NAND_SUNXI to NAND_SUNXI ... Browse Code »

    We eventually want to add full nand support, since it makes no sense
    to build SPL with nand support and u-boot without, or the other way
    around, a single option will suffice.

    Renaming the Kconfig option now makes things easier when we add full
    nand support in the future.

    The "obj-$(CONFIG_NAND_SUNXI) += sunxi_nand_spl.o" is moved to an
    "ifdef CONFIG_SPL_BUILD" block in the Makefile.

  • 2b8a01a99   sunxi_nand_spl: Auto detect nand configuration parameters ... Browse Code »

    Auto detect the nand configuration parameters, like the BROM does.

    This allows us to get rid of various Kconfig settings, and is
    necessary to support generic boards like the mk802 which have seen
    many production runs with different nands.

    The full blown u-boot/kernel nand driver uses the nand id to determine
    this info, for the SPL we do as the BROM does and simply try a few
    standard configs.

    Note the table only contains configs which are known to actually be used,
    rather then all the configs the BROM tries. This means that it may need
    to be updated in the future as we add support for nand on more boards.
